Description
BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention generally relates to vehicles and more particularly to pilot seating having integrated flight controls and adaptable passenger seating.

2. Background of the Invention

Conventional aircraft are characterized by massive instrumentation positioned in front of the pilot seat, with manual flight controls including cyclic, collective, anti-torque pedal mechanisms, and throttle controls that are often integrated into the collective control. As is well known, the cyclic control is typically configured like a joystick to enable the pilot to vary the pitch angle of ailerons or rotor blades so that the angle of attack can be changed to control the lift and direction of motion of the aircraft, forward, backward, sideways, hovering, etc. by producing a thrust vector to accomplish the needed operation.

In airplanes, the throttle allows the pilot to change the mass flow-rate of air (in fuel-injected engines) or air/fuel mixture (in carbureted engines) delivered to the cylinders. In helicopters, the collective control allows the pilot to change the pitch angle of all of the main rotor blades simultaneously and together to increase or decrease the lift provided by the main rotor or to produce acceleration together with an increase in the total lift during a climb or ascent. The anti-torque pedals—there are usually two—allow the pilot to change the tail rotor blade pitch to increase or decrease the thrust to produce a nose yaw to the left or right as needed to maintain a steady orientation of the helicopter during flight. The throttle, of course, is used to control the power developed by the engine(s) that drive the rotor. For each function, there are one or more components corresponding to such function, cluttering an already cluttered cockpit and adding unneeded complexity.

During travel, a passenger is subjected to myriad forces that can jostle the passenger in his or her seat. Typically, aircraft include conventional passenger seats having straight backs, seats, and arm rests. Such configurations are static, uncomfortable, and provide little support to counteract the rigors forces exerted during often turbulent travel. Newer aircraft attempt to provide support via modest cushioning and cantilevered headrests. None of which provide any stability for the passenger's body.

There is thus a need for seating that lacks these disadvantages so that an aircraft that is efficient, safer to operate, more comfortable, and can benefit from updated flight control mechanisms.
